Answer:
An Access control list (ACL) is used to describe a list of security policies that is associated with an object
Answer and Explanation:
Given that total number of records in a file = 100000
Each record consists of= 240 bytes
Given that B= 2400 bytes.
Then total blocks in file = 100000 records * 240 / 2400
= 10000 blocks.
Time that will take for exhaustive read
= s + r + b.btt
= 16 + 8.3 + (10000) * 0.8
= 8024.3 msec
Now as per given X be the number of records that are searched randomly and it takes more than exhaustive read time.
Hence, X (s + r + btt) > 8024.3
X (16+8.3+0.8) > 8024.3
X > 8024.3/25.1
So that, X > 319.69
Hence, atleast 320 random reads should be made to search the file
Answer: Algorithm
Explanation: An algorithm is a plan, a set of step-by-step instructions to solve a problem. it involves three basic building blocks to use when designing algorithms. these are.,
1. Sequencing
2. Selection
3. Iteration
Question:
Write one for loop to print out each element of the list several_things. Then, write another for loop to print out the TYPE of each element of the list several_things.
Answer:
The solution in python is as follows:
for element in several_things:
print(element)
for element in several_things:
print(type(element))
Explanation:
The solution assumes that the list several_things has already been initialized.
So, the rest of the code is explained as follows:
This line iterates through the list, several_things
for element in several_things:
This line prints each element
print(element)
This line iterates through the list, several_things for the second time
for element in several_things:
This line prints the type of each element
print(type(element))
